Influence of Albit on onion was examined in trials carried out by All-Russia Institute
of Vegetable Selection and Seed Breeding on onion varieties Shtuttgarterrizen
and Alvina (2003 and 2004). In the trials, onion was grown in greenhouse
conditions for scallions.
According to results of trials, Albit provided average increase of scallion yield
by 9-29.6%, lenght of leaves by 12.6-21%, dry weight of leaves by 7.4-10.7% (nutritious
value), content of clorophyll (by 6.2-40.8%) and ascorbic acid. Also, Albit decreased
content of nitrates by 74-77 relative %. In conducted trials, economical or biological
effectiveness of Albit was not inferior to that of standard formulations based on
epibrassinolide.
It is recommended to perform presowing soaking of onions for 1 hour in Albit solution
(5 ml/L). Recommended application rate of the biopesticide is 5 ml/kg of onions; consumption
of working solution is 1 L/kg. Cost of such treatment of 1 kg of onions is 11 roubles
(0.44 USD).
Trials on onion and lettuce demonstrated that Albit
is highly efficient for increase of yield and improvement of quality of grrenhouse
vegetables.
